IMPROVEMENT IN- COOLING AND PRESERVING BEER AND OTHER LIQUIDS 0N DRAFT,

Specification forming part of Letters Patent No. 115,468, dated May 30, 1871.

Be it known that I, JOHN M. HEIss, of Baltimore, in the county of Baltimore and State of Maryland, have invented anew and useful Device for Forcing Beer and other Liquids out of Kegs, Barrels, 850., and Cooling the same;

andLdo hereby declare that the following is a full, clear, and exact description thereof, sufficient to enable those skilled in the art to which. my invention appertains to make and use'the same, reference being had to the accompanyin g drawing making part of this specification, in which- Figure 1 is a verticalview of my improved "device, and Fig. 2 is a top View of the same.

Similar letters in thegdrawing denote like parts." i

The nature of my invention consists in using two b0ilers,.of copper, iron,.or other suitable material, holding compressed air, by which the liquid is forced through or out of the vessel containing it, then passes a long pipes, constructed for the purpose, lIllJO, a receiver, where ice-cold water surrounding the pipes keeps them cool, and consequently the liquid contained therein. The air is compressed by inserting withforce into the aperture A a sufficient-quantity of water to compress the air within thebo'iler, while thecocks or faucets J J admit of the contents being emptied whenquired for use. The pipe 0 is the conductor, by which the air'is conveyed from the first or original boiler to the second. The gage E shows'thedegree of air force used, and the pipes F F, ofthe same. material as the pipe from the boilerinto casks L L, kegs barrels, &c., which may contain the fluid to be acted upon. These last pipes have also stopcocks ried into the receiver M, the pipes there wind- V ing around in a serpentine manner. The iceboxN is filled with ice, and the water therefrom 4 is conducted by 'thexpipe 0 into the receiver,

whereit falls and rests upon the pipes containin g the fluid, thus cooling them, and consequently the fluid inside. e

v G G to out off the supply of air whenever nec- The principle is precisely the same, although the arrangement is somewhat different, as

shown by]? P, where my invention is applied to a soda-water fountain.

Whatever waste water may be accumulated in the ice-box is provided for by a pipe fastened underneath, as shown by p, with a cock attached.

What I claim as my invention, and desire to secure by Letters Patent, i's

The combination of the boilers B B, the pipes O, F F, and H H, with their respective cocks and gage, acting upon any number of kegs, barrels, &c., that may be desired, together with the receiver M and its pipes, and the ice box or chest N, the whole arranged for the purpose herein set forth, and substantially as described.

The above specification signed by me this 24th daylof February, 1871.
